How to use jqGrid with C#/ASP.NET and JSON.NET (and no AJAX.NET stuff)?

Question

OK, I've been looking into this a few days and am not particularly sure what I am doing wrong. If anyone has working examples of using jqGrid with C#/ASP.NET and open source tools, please, please let me know where to find them. Any tips on finding decent documentation or tools I could use to debug this would be most appreciated too (I'm pretty new to js/jQuery). Basically I just need the edit-in-place functionality, so if I'm overlooking another obvious solution for that, it could be helpful to know... I'd like to avoid using AJAX.NET if at all possible. I feel like I'm just overlooking something really obvious here. In the following example, I do get the jqGrid to display, but it shows no data. Here is the relevant JavaScript: ``` jQuery(document).ready(function(){ jQuery("#role_assignment_table").jqGrid({ url:'http://localhost:4034/WebSite2/PageItemHandler.asmx/GetPageItemRolesJson?id=3', mtype: 'GET', contentType: "application/json; charset=utf-8", datatype: "jsonstring", colModel:…

Accepted Answer

Before doing anything else, download and install this:

http://www.fiddler2.com/fiddler2/

It will let you see exactly what is being requested and sent back by the jqGrid requests to get the JSON data.

I have some code for a working jqGrid, and here's something different:

```
datatype: "json"
```

Instead of your:

```
datatype: "jsonstring"
```

I also have a field called `colNames` which is an array of strings containing column names.

Finally, I have a `pager` field which identifies an element that will store the paging controls, and is a DIV.
